Classification Bathyteuthoidea unranked clade in Tree of Life, here ranked as superfamily reflecting that the included genera Bathyteuthis and Cthenopteryx are now in separate families but have been considered long in the same family (e.g. Naef, 1921) and that molecular data confirm their close relationship one to another (Carlini, 1998: Ph.D. thesis cited in Tree of Life page).
